s claims. (ci. 53-6) This invention relates to baking pans and the material from which they are made, whereby the pan will present a pleasing and appealing appearance, will not be easily scarred or marked,

5 and will have increased strength and resistance to denting and warping. It also contemplates a pan wherein the grease, if any, used in baking will be evenly distributed over the inner surfaces of the pan and the pan surfaces in direct contact with the dough therein will be increased to improve the bake.

With the above and other objects in View, as will be apparent, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein: l

Fig. l is a fragmentary corner elevation of one type of pan. embodying the present invention;

Fig. 2 is a similar view of a munn frame illustrating the present construction incorporated therein;

3 likewise is a fragmentary elevation of 'a plate showing the present invention as applied thereto; and

Fig. l is a section through a wall of a pan made in accordance with this invention to illustrate the formation and construction thereof.

Heretoiore, in the manufacture of baking pans 3@ the material or metal used has generally had a plain, smooth, uninterrupted and generally a polished surface with the result that every defect in. the material, all dents placed therein from one canse or another and all finger prints, smndges, and the like appeared thereon and often were emphasized. Therefore, the smooth, plain, polished. surface of the pan walls in addition to being sily marred and dented, did not present a pararly attractive appearance on display, espey after the article has been frequently han Chai.

lin addition to this, the average baking pan de ci smooth, hat material warps easily and uently becomes distorted unless the gauge or Nsness of the metal from which the pan is is greatly increased.- rhis is particularly true oi relatively large and shallow pans such cookie sheets. It is customary to grease the interior of a baking' pan prior to placing the therein and in the pans prior hereto the oot'n uninterrupted surfaces thereof have proi ded no means for holding such grease and causan even distribution thereof.

The present invention contemplates a baking pan will overcome the objectionable features the entire pan surface.

of the prior pans, by providing an over-all geometric design or pattern in one or more of the pan walls which will produce a series of alternate depressions and elevations throughout the lsurface of the pan wall. When the material of the pan is thus treated by having an over-al1 geometric design or pattern. impressed or formed therein, the pan will be greatly strengthened and the appearance vastly improved. The forming of an over-al1 pattern or design in the material of the pans removes all stress, strains, and buck les therefrom and conceals any and all defects which may occur in the material. Furthermore, pans so constructed may be readily handled during the display thereof without iinger prints or smudge being obvious and glaring.

Certain types of pans such as cookie sheets when made of smooth, flat sheets Warp readily and do not ship flat, whereas, when made in accordance with the present invention additional strength is provided throughout the walls, as well as at the edges thereof to prevent warpage and to maintain the pans at all times relatively ilat.

By having the alternate depressions and projections over the surface of the pan wall or walls, the heating surface contacting with the contents of the pan is materially increased and there is a more uniform distribution of the grease over In this manner the baking in a pan made in accordance with the present invention is greatly improved over that in the pans with smooth dat walls.

Reference being had more particularly to Figs. 1, 3 and 4l of the drawing, l@ designates the walls, either side or bottom, of a baking pan. These Walls it are formed from sheets of any suitable metal and have alternate depressions il and elevations l2 created therein by stamping, rolling and by any other suitable means. The formation of the depressions l l in one face oi the wall i@ creates the elevations l2 on the opposite face of the wall, so that .the depressions ll and elevations l2 of one face of the wal-l are complemental to the simiiar elements of the opposed face of the wall. l

The elevations il and projections I2 may be arranged in any suitable pattern, two examples of which are shown respectively in Figs. 1 and 2 of the drawing. By reference to Fig. 4 of the drawing it will be observed that the depressions il and elevations i2 may, if desired, be formed with the facets I3 which add to the strength of the Wall and present a pleasing and attractive appearance.

In Fig. 2, showing the present invention applied to a muin frame, the vpattern is not applied to the cups Iii, but is applied to the sheet or frame I5 in which the cups are carried. In this form 0f the invention the frame or sheet I5 is greatly strengthened and its appearance vastly improved.

In Fig. 3 is shown another application of the present invention, viz. the application thereof lto a pie plate. Here the side wall I6 of the pan is plain but the bottom IIJ thereof has the present invention applied thereto.

In practicing this invention the alternately arranged depressions II and elevations I2 arranged in any suitable pattern or design may be rolled,`

impressed or otherwise formed on the sheets of metal from which the pan is made prior to the formation of the pan, or may be formed in the pan walls during or after the formation of the pan. It has been found that where the sheets from which the pans are to be made are provided with the alternately arranged depressions and elevations II-I2, the same can be readily rolled into the metal but where they are placed 'in the pan wall or walls during or after the formation of the pan, it has been found desirable to do this by a stamping operation.

From the foregoing, it is manifest that the strength of the pan is greatly increased by the construction herein described; that dents, scars and defects in the metal will not be apparent; that any grease applied to the interior surfaceo! the pan will settle and be held by the several depressions II and that the provision oi facets I3` in combination with the depressions Il and elevations I2 will create an extremely attractive and pleasing article.

What is claimed:

1. A sheet metal baking pan having a bottom stamped into alternate elevations and depressions, aligned in at least two directions.

2. A sheet metal baking pan having the material thereof stamped into alternate elevations and depressions aligned in at least two directions.

3` A sheet metal baking pan having a series of alternately arranged relatively shallow depressions and elevations aligned in at least two directions.

4. A sheet metal baking pan having a plurality of relatively small, shallow depressions formed therein arranged in rows in at least two directions, said rows being separated one from the other by continuous, relatively low and narrow elevations.

5. A sheet metal baking pan having a series -ofsha11ow, relatively small depressions formed in the bottom thereof and aligned in rows in at least two directions, said rows being separated one from the other by relatively low and narrow elevations, part of which are continuous and part interrupted by other elevations.

6. A metal baking pan having a plurality of separated relatively shallow, small depressions in the bottom and walls thereof.
